device connected to pin X1_CPU.
PLL (f
master clock output up to 96 MHz (programmable). By default, at power-up the master
clock is sourced from the main oscillator until the PLL is ready (locked) and then the
CPU may switch to the PLL source under firmware control. The CPU can switch back to
the main oscillator source at any time and turn off the PLL for low-power operation. The
PLL is always turned off in Sleep mode.
RTC (f
X2_RTC, or an external oscillator connected to pin X1_RTC to constantly run the real-
time clock unit. This 32.768 kHz clock source can also be used as an input to the CCU
to run the CPU in slow clock mode for reduced power.
